Tesseract - Different result between demo and node-red

I'm trying to make the "node-red-contrib-tesseract" working with my application.
I need to get the text from a recepit.
In the demo work flawless without problem even using eng language ( lang is ita ) but in node-red is not getting the correct text.
Some one as any idea ?
Are they different version of tesseract?

Most likely this is due to the node red contrib node not being updated for the last 3 years. If you look in the githib repository for this node you can see it's dependency is set to version 1.x of tesseract.js. On NPM, version 2.x of tesseract.js is available.

I suggest you contact the author of this node and enquire about getting it updated.

Alternatively, fork it and publish a PR back to the node - hopefully the author will merge that.

Will be hard to do so?
Are there any guide for newbie ?

Thanks for your answer.
